One can only wonder how long Nic Grigsby will continue to be Winnipeg’s starting running back.

The former Arizona Wildcat had 10 carries for seven yards — yes, you read that correctly — in Thursday’s 23-17 home loss to the Saskatchewan Roughriders. It didn’t sting the Bombers too much because the offence did pretty well on second-and-long, but the run game is a disaster right now.

On Saturday afternoon, Bombers head coach Mike O’Shea placed the blame all over the place. Not even quarterback Drew Willy was excused from the list of culprits who have made Winnipeg’s rushing numbers the worst in the league.

“It’s never one thing,” O’Shea said. “That’s the issue, is generally a few mistakes on the same play that cost us, that allow us to get caught in the backfield. Could be footwork by an offensive lineman, could be a cut by a running back, could be line of the quarterback, could be blocking of a slot coming in to chip. It could be all those things."
